Zig, though, does very clearly lay out its pitch right on the homepage, and although it's maybe not a table of checkmarks, it's a series of pretty clear shots-across-the-bow at other languages, in particular C and C++.
Rust similarly has a "Why Rust" block above the fold on its homepage; it's not quite as terse as the Zig one, but it's clearly that same executive-level pitch.
Hare's homepage has: "Hare is a systems programming language designed to be simple, stable, and robust. Hare uses a static type system, manual memory management, and a minimal runtime. It is well-suited to writing operating systems, system tools, compilers, networking software, and other low-level, high performance tasks."
Maybe there's a case to be made here that these bald assertions are no different than what Zig and Rust claim about themselves. But I also think it's reasonable to have different expectations around this for a brand new project vs ones with years of track record and existing mindshare.
